Answer: When two polynomials are multiplied, the product is always a
polynomial.
Step-by-step explanation:
The only true property for polynomials is the third options because when you do multiply polynomials, you can only get a polynomial.
For instance;
Multiply (5x – 6y) by (7x – 4y)
= (5x – 6y)(7x – 4y)
= 35x² - 20xy - 42xy + 24y²
= 35x² - 62xy + 24y²
The result is a polynomial.
The rest of the options will not always yield polynomials.
Answer:
The answer is -456 feet per minute.
Step-by-step explanation:
They are asking for the average elevation change per minute. Since there are 7 minutes, you would divide -3,192 by 7, and that would result in -456
You add 5 3/4 and 4 1/4 and your answer should be nine and 44
Answer:
D
Step-by-step explanation:
The measure of x is calculated as
x = 0.5( arc CD - arc BD)
= 0.5(210 - 72) = 0.5 × 138 = 69 → D
